well 3v0 you have some right. i'm electronic engineer, so i know what i'm doing with this stuff. it is not my first pc upgrade. i have upgrade my old pc with the 4CoreDual-SATA2 R2.0 mobo because i didnt want to upgrade all the parts of the pc. so i keep my wd400 hard disk(40GB), dvdrom toshiba and the MSI fx5900zt-vtd128 graphic card. i also put a cpu from a friend. a pentium D/3ghz/830/800fsb/2chache. i put all cables and this is the point that i meet for the first time of my carrier. when i turned on the switch of the PSU the pc starts immediately without wait me to push the start button of the pc. strange for me. the screen shows nothing. i think it is a fault processor but i don't have another to test. also i measure the volt at the pins of the start, reset buttons and the pins of the disk and power leds on the motherboard.
all is OK, but i'm measuring 5V at the -powerled pin and 2.5V at the +powerled pin.
when i triggered the power or the reset pins while the pc running nothing happens, no restart no shut down.
is this a faulty motherboard? please give me your lights.
regards,
Jimi.
